Police said they arrived at Brown’s residence in the 5300 block of St. Anthony Avenue about 12:30 p.m. Sunday and found the boy dead. The next day, according to a warrant drawn up by homicide Detective Jana Thompson, Brown came to police headquarters of his own accord to offer a statement.

Police said Brown provided “several versions” of what happened.

“Eventually he admitted to shaking the 2-month-old infant and that the infant fell to the floor,” according to the warrant. “When the infant stopped crying, Mr. Brown Sr. placed the child back into the bed and left the residence.”

The child was later found not breathing by a relative, police said. He was pronounced dead on the scene about 12:40 p.m.

Willard Brown disputed the New Orleans Police Department’s claim that his son admitted on tape to shaking the child.

Willard Brown said investigators told him the baby had injuries from fractured ribs that were weeks old, and he is looking into where the injuries came from.

“This is my baby boy,” he said of his son. “I’m going to turn over every stone. Something is just not right.”

The younger Brown remained in jail Monday. His next court date is set for March 22.
